So I have an old and fairly rare Ampeg SVT-100 head. It sounds lovely! Unfortunately, it doesn't have a DI, because it is very old and was made on the cheap during one of Ampeg's numerous corporate transitions. I'm been GAS'ing for one of the small Ampeg portaflex amps, the PF-20t and PF-50t, mostly because they have the cool "transformer DI" that you can run (1) without a speaker and (2) after the power amp transformer, so it sounds more like the full amp's section. I also just got done recording on a vintage B-15 and desperately want to be able to take that sound with me. Is there anyway to higher an amp tech to retrofit a similar set-up into my SVT-100? Obviously, the cheapest answer is "buy a DI and take it with you, then plug the effects out into the DI" but my head doesn't even have a pre-amp out, so there's no way to get ANY of the amp's sound/mojo into a DI. Thoughts TB community? Doable or nah?
